useful Improvements in Suction Valves for Cigarette Lighters; and I do declare the following to be a full, clear, and exact descri 'tion of the same,'reference being had to t e accompanying drawings, and to the characters of reference marked, thereon, which:

.--form a part of this application.

This mventionrelates to improvements a suction-control and switch actuating mom her .to be used especially in connection with my ci arette dispenser and lighter, applications or patent on which are copending, the

original valve over which the present one is an improvement being particular] shown in application, Serial No. 616,906, ed Februaryfth, 1923. I n e principal object of the present invention is to provide a valve for the purpose to open the suction, close the lighter switch and force the cigarette into enga ment with the lighter, arranged to be readl y moved to functlon as above, and which when somoved will remain in such position without further attention or effort on the part of the opera-v tor, until an intentional retractive movement is imparted to the valve: The present va'lve also has less tendency to leak than the previous one. i -A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedin 1y effective or the purposes for which is is esigned. These objects I accomplish by means 'of such structure and relative arrangement of parts as will fully appear by a erusal of the following specification and c aims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a front elevation of the complete container, dispenser, and lighter, showing open position.

Figs. 2 and 3 are sectional views of the valve, showing the same in its closed and open positions respectively.

Fig. 4 is a cross section of the valve on the line H of Fig. 3.

Referring now more particularly to the characters of reference on the drawings, the

numeral 1 denotes the frame or casing of the device, adapted to be secured onto a dashboard or the like, provided in connection with which are the cigarette containing means 2 and dispensing means actuated by the cigaretteon the supportsand beyond the same is an electric heating element 6, a lead 7 from; which extends to a contact strip 8 mounted onand insulated from the frame 'ad'acent the opposite side thereof.

ixedon sai op site side of the frame inalinement with e element 6 is a sleeve 9.havinga peripheral and diagonally or spirally extending slot 10 of certain length .eut therethrou h.

A radially 'sposed passage member 11 taps the sleeve intermediate its ends and in opposed relation to the plane of the slot 10, the outer end of said member being tubular in form and arran to receive the 'end of a suction tube 12 t ereover.

Mounted in the sleeve 9 with a sliding and turning fit is a c lindrical valve member 13, having at its en facing the element 6 a cup or cone sha d dGPIGSSlOD 14 adapted to fit over the a jacent end of the cigarette on the su ports 4.

Lea 111g inward from said depression is a passage 15 terminating in a eripheral port 15 intermediate the ends of t e valve. A

A spring 16 is seated in the member 13 at a point opposite to the port 15, sad spring pressing against the inner wall of the sleeve to prevent undue freedom of movement less of wear.

A radial stem 17 forming a handle, is fixed on the valve 13 and projects through the slot 10. The handle and port 15 are so disposed relative to each other and to the slot 10 and assage 11 respectively that when the ban le is at the outer end of-said 'slot, the valve 13 is then telescoped completely in the sleeve 9, and the port 15 lies to the rear of and above the passage 11. It will therefore be evident that for any air leakage to be had between the rotation of the valve, the port 15 is moved to aline with the w 11, thus opening a continuous pa from the cup 14 to the suction tube 12, the spring 16 then forcing the adjacent surfaces of the sleeve and valve into close contact.

Also with the advancement of the valve, the latter comes into contact with the strip 8 with a good wipin action, insurin a good contact bein ma 0 at all times. '5

contact causes the eater circuit to-be closed. When the valve has been moved to its last named or operating position, it will remain in such position as long as may be desired, without the necessity of [the operator maintaining a grip on the handle. From the foregoing description it will be readily seen that have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what -I claim as new and useful and desiretosecure by Letters Patent is:

1. A suction valve member comprising a sleeve, a pa member leading to the pe-. riphery t, ereo a valve in the sleeve having a peri heral port, said port space from the sleeveedto be alined therewi mg1 salid valve in a mannbeerlto the port an S66v6 rea ain 1- means between the sleeve and valve th p x 'g vent undue freedom of movement of the latter.

2. A 'suctionvalve member comprising a sleeve, a tgases e member leading to the periphery efleo ,1 a valve the m havmg a perip era port sai rt normallyspaced from the sIee ir L-pe but adapted to be alined therewith, means for moving said valve in a manner to cause the port and sleeve passage to be alined, and

spring means between the sleeve and valve to prevent undue freedom of movement of the latter, and also acting, when said rt and passage are alined, to force the jacent surfaces of the sleeve and valve wh ch surround said port and passage into close contact.

In testimony whereof I aflix my signature.
